A SUPPORTING PROCESS BY DAMAGE HIERARCHY ANALYSIS FOR BRIDGE MAINTENANCE

[ Abstract ] In this paper, to support decision making in bridge maintenance, an approach by damage hierarchy analysis is proposed. Firstly, by ISM, the relations between causes and effects of bridge damages are discribed as hierarchy. Secondly, each link of hierarchy is given a numerical value as the influence of damage factor, and analysis is made by SAD. Finally, the repair alternatives are evaluated by Al-IP. The presented approach is realized by successive application of different analysis method to a problem on a personal computer system.

COLOR HARMONY ANALYSIS OF BRIDGE SCENERY

本研究では, コンピュータ上の橋梁景観画像をマンセル表色系に変換することで既存の色彩調和理論の応用を試みたものである. まずパーソナルコンピュータ上でRGBカラーモデルとマンセル表色系との相互変換を実現した. 色彩調和理論としては定量的な定式化が容易なムーン・スペンサーの色彩調和論を採用した. 分析結果はアンケート調査結果との比較によりその妥当性を検証した.
